Phys. Rev. D 72, 067301 (2005) [4 pages]Preclassical solutions of the vacuum Bianchi I loop quantum cosmologyReceived 13 May 2005; published 12 September 2005 Loop quantization of diagonalized Bianchi class A models, leads to a partial difference equation as the Hamiltonian constraint at the quantum level. A criterion for testing a viable semiclassical limit has been formulated in terms of existence of the so-called preclassical solutions. We demonstrate the existence of preclassical solutions of the quantum equation for the vacuum Bianchi I model. All these solutions avoid the classical singularity at vanishing volume. © 2005 The American Physical Society URL:
